I think it would be great to add more features to the tile cards like rgb color selection, white color temperature, drop down lists for various devices that have selectable options.
Maybe this should be a separate topic but also being able to control visibility of these features like you can do with cards overall now. Example: Simple tile card when device is off, but when device is on the brightness and effects drop down list are now visible in the card.
Love the Tile card. But the one thing I am missing is adding a value of another entity to the state output. Specially of my power plug (switch) showing current power usage when on (sensor).
100% agree for the need for more features and the color picker for lights !
moreover, for the existing features, they need to be consistent with the state of the entity:
For example for lights: color temperature slider should not be orange when light is switched off, but the same grey as the light intensity…
